Cloudflare Containers Addresses Security Issue: Flaw Allows Access to Leftover Disk Data
Cloudflare, a popular web performance and security company, has announced the discovery and subsequent fix of a security flaw in its Cloudflare Containers service. The flaw allowed a paying customer to access data left behind by other customers on the same server.
The vulnerability occurred when a paying customer's container accessed disk space that had been previously used by other containers but had been released. Researchers and Cloudflare stated that the accessed data originated from leftover disk space and not from active workloads. Furthermore, an attacker could not selectively choose which customer's data to access.
Cloudflare took prompt action upon discovering the issue, working with the researchers who identified the flaw to resolve the problem.
